I'm looking to get into an old D&D game. I got some D&D collection with a bunch of REALLY old games a couple years back (Menzoberranzan, Dungeon Hack, etc.)  But now I'm looking to get into a slightly more updated one.  To be honest, I probably will only play one of these - so don't give me a long list of what order I should play them in. For example - if Baldur's Gate 2 is better, I'd rather play that then go back to part 1, even if some story elements make that hard. So, recommend away, and explain yourself!        

Well, I've truthfully only played NWN, so that's what I voted for. I recall having a blast with that game.

  Baldur's Gate 2

I'd probably go with Baldur's Gate 2.

NWN2 or BG2
NWN2 is a little better though.

Stay away from Neverwinter Nights 2, it's trash. You should try the Baldur's Gate series as well as the original Neverwinter Nights.

Anyone played Icewind Dale games? I read the books and loved them, but I realize that might not be the best reason to get the games.

Those all sound good!

I'm currently playing through Baldur's Gate II for the first time but after playing Neverwinter it's kind of hard to handle; the interface just feels so archaic. But I got used to Fallout 2 so we'll see how it goes.

Neverwinter Nights is great, and the community was still going strong about two weeks ago.
